| mulbah | Good morning Mr. Cole | 12:59 |
|---|---|---|
| ubuntourist | Hi mulbah | 12:59 |
| mulbah | How are you doing | 12:59 |
| ubuntourist | A bit of a headache this morning... stuffy sinuses, but other than that, good. | 13:00 |
| ubuntourist | And you? | 13:00 |
| mulbah | I'm okay | 13:00 |
| ubuntourist | So, have you had an opportunity to either explore fields on your own or talk with tboimah? | 13:01 |
| sysadmin_ | Good morning ubuntourist | 13:02 |
| ubuntourist | hi tboima | 13:02 |
| tboimah | I am Good | 13:03 |
| ubuntourist | I was just saying I've got a bit of a sinus headache this morning, but basically okay myself. | 13:03 |
| tboimah | okay | 13:03 |
| mulbah | This gone week I was busy on graduation but I'm done with it now | 13:03 |
| mulbah | I graduated this gone friday | 13:04 |
| ubuntourist | tboimah, I was checking with mulbah before you came on to see how the exploration of fields and field delimiters was coming. | 13:04 |
| ubuntourist | tboimah, mulbah, I should learn if your course study is similar to the courses taught in the US. | 13:05 |
| *** tboimah has quit (Remote host closed the connection) | 13:05 | |
| mulbah | I don't think so | 13:06 |
| ubuntourist | Actually, because I do not have children, I would be comparing it to what I remember of my high school studies which were quite a while ago. | 13:06 |
| sysadmin_ | what is the course taught in the US | 13:06 |
| ubuntourist | I mean, over four years from grades 9 to 12 (ages 13 - 17, typically) we had: | 13:07 |
| *** sysadmin has quit (Ping timeout: 480 seconds) | 13:08 | |
| ubuntourist | Science: Introduction to Science, Biology, Chemistry, Physics | 13:08 |
| ubuntourist | Mathematics: Algebra, Geometry, Trigonometry, Calculus | 13:08 |
| ubuntourist | English - four years of English. I don't remember a specific focus for each year.. | 13:09 |
| ubuntourist | Foreign Language: We were required to take two years, but could choose between Spanish, French and German. | 13:10 |
| ubuntourist | Social Studies / History / Geography - I did poorly and don't remember much of these, though I liked ancient history -- especially Greek history. | 13:11 |
| ubuntourist | Also, we had room for a few "electives" I chose to take some Art classes and Mechanical Drawing / Drafting classes. | 13:13 |
| ubuntourist | The reason I'm asking about your curriculum is that it may help me know what it is you've learned and which things I can use as examples. | 13:14 |
| ubuntourist | I was thinking about "What examples of fields would I have seen in grades 9-12?" | 13:14 |
| sysadmin_ | ubuntourist there was a project given to us, so that we can the configure a sever so that the user will be be able to login the server with a hostname instead of the IPadress, and try our best in doing it but we have some problem, and we really need your help please. | 13:15 |
| ubuntourist | And my first thoughs were "BIology and chemistry" | 13:15 |
| ubuntourist | sysadmin_, OK, a project... Cool. | 13:17 |
| ubuntourist | sysadmin_, is this a new server? And is it on the internet now? Can it be accessed remotely? Or only from within the school? | 13:18 |
| mulbah | it can be assess remotely | 13:19 |
| sysadmin__ | it is a new server and it can be accessed remotely | 13:19 |
| ubuntourist | So, what's the IP number? | 13:19 |
| sysadmin__ | mulbah please send me the IP number and the password privately | 13:19 |
| *** tboimah has quit (Ping timeout: 480 seconds) | 13:20 | |
| tboimah | it is tboimah not sysadmin | 13:20 |
| mulbah | I | 13:20 |
| mulbah | send he it | 13:20 |
| tboimah | i also need | 13:20 |
| ubuntourist | Oh, by the way, I have an important trick I just learned: | 13:20 |
| tboimah | mulbah i also need that | 13:21 |
| ubuntourist | There is a way to add weak encryption to IRC so that the logs cannot be read | 13:21 |
| ubuntourist | by people without a password. (It is not very good encryption, but it is better than plain-text, which | 13:21 |
| ubuntourist | is what we are using now.) | 13:22 |
| ubuntourist | Unfortunately, I forgot to take notes, and will need to dig that up again. | 13:24 |
| *** sysadmin_ has quit (Ping timeout: 480 seconds) | 13:24 | |
| ubuntourist | We should probably explore encryption, digital signatures and checksums. (The three are all related to each other..) | 13:26 |
| ubuntourist | It would allow for sharing secret information between trusted parties. | 13:26 |
| ubuntourist | So. | 13:27 |
| ubuntourist | Is this a new server? | 13:27 |
| tboimah | mulbah can you also send me the password for the server also | 13:27 |
| tboimah | yeah | 13:27 |
| ubuntourist | If it is on Linode, and provided through NOVA Web Development, I can probably look up the info, | 13:28 |
| ubuntourist | ACTION is checking now... | 13:29 |
| tboimah | i think it is a Hexznet | 13:30 |
| tboimah | something like that | 13:31 |
| ubuntourist | Hmmm... OK... You may need to get help from someone other than me. | 13:31 |
| mulbah | i send you message | 13:31 |
| mulbah | thomas | 13:32 |
| tboimah | what happen ubuntourist | 13:32 |
| tboimah | I have the password now mulbah | 13:32 |
| ubuntourist | Hold a sec... | 13:34 |
| ubuntourist | Back again. | 13:35 |
| sysadmin_ | So Mr Cole can you help us | 13:36 |
| ubuntourist | What you need to do is either throuhgh your service provideer (Hexznet) or through a Domain Registry company like Namespace, | 13:36 |
| ubuntourist | you will need to first select a domain name (something.net, or something.org, or something.com, or... many choices...) and then, | 13:38 |
| ubuntourist | after the domain name has been purchased, tell one of those two (Hexznet or Naomespace) to associate the number with the domain name you have | 13:39 |
| ubuntourist | purchased. | 13:39 |
| ubuntourist | Eash company has a different way of doing that. | 13:39 |
| ubuntourist | I have only done that once, using Linode and Namespace. I will need to look through my notes refresh my memory on the procedure I used. | 13:40 |
| ubuntourist | I suspect you will need to ask Spencer or someone else to help you navigate this problem. | 13:41 |
| *** tboimah has quit (Ping timeout: 480 seconds) | 13:41 | |
| sysadmin_ | The server has already been purchased and we already have the domain name and the IPadress, what they want is for the to be able to login the server with the domain in stead of the IPadree | 13:41 |
| sysadmin_ | spencer do not have idea on it also | 13:42 |
| ubuntourist | It will be done usually via a web page from the service provider (Hexznet). | 13:43 |
| ubuntourist | Or maybe Namespace. Whichever company you used to register the domain name will have a "control panel" on a web site that | 13:46 |
| ubuntourist | will let you associate the name with an IP address. | 13:46 |
| ubuntourist | (According to my command line tool "nslookup" your domain is currently associated with the domain "cleancookingsystem.org.cn"... | 13:47 |
| ubuntourist | I hope that is old, out of date information...) | 13:48 |
| ubuntourist | (Once you have successfully associated the IP address number with the domain name, it may take one or two days for it to succeed: | 13:49 |
| ubuntourist | The assiciation between the name and the address must be "propagated" -- spread -- to all of the Domain Name Servers (DNS) so that everyone in the world | 13:51 |
| ubuntourist | knows about the link between the two.) | 13:51 |
| ubuntourist | ACTION needs to step away for a minute | 13:52 |
| ubuntourist | ACTION is back | 13:57 |
| ubuntourist | ACTION is searching through notes on how he made this link between IP address and domain name... | 13:58 |
| tboimah | please ssh e5G9HGfE4eJN4hCwCdR354SDh@lon1.tmate.io let me show you something | 13:59 |
| *** mulbah has quit (Ping timeout: 480 seconds) | 14:01 | |
| mulbah | hello | 14:17 |
| ubuntourist | mulbah, Sorry. I am in the tmate session. | 14:18 |
| ubuntourist | # newport is frozen | 14:28 |
| sysadmin_ | ssh bRG4xUr4aR6ED3fNTPZh6EDCH@lon1.tmate.io | 14:31 |
| sysadmin_ | please ssh into that ubuntourist | 14:32 |
| *** tboimah has quit (Ping timeout: 480 seconds) | 14:33 | |
| tboimah | ubuntourist are you there | 14:34 |
| ubuntourist | Yes. | 14:35 |
| ubuntourist | tboimah, yes. Watching you edit. | 14:35 |
| ubuntourist | I would add the space | 14:36 |
| ubuntourist | sp tjat ot still lines up | 14:36 |
| ubuntourist | tboimah, I mean, a space where you uncommented. | 14:36 |
| ubuntourist | Now for it to take effect, ssh server must be restarted. | 14:37 |
| ubuntourist | systemctl is the program used to start, stop, restart, enable, and disable various | 14:40 |
| tboimah | ssh DvZ8TzLyAEmV5uBdHcTgDhL6D@lon1.tmate.io | 14:40 |
| ubuntourist | system services -- also known as daemons | 14:40 |
| tboimah | ssh in that to go to newport | 14:40 |
| ubuntourist | servver is rebooting... | 14:51 |
| ubuntourist | Network keeps freezing on me, | 14:55 |
| tboimah | hmmm | 14:55 |
| ubuntourist | This looks like a job for stackoverflow or segfault... | 14:56 |
| ubuntourist | Time to reach out to the web. Checlking those forums now.. | 14:56 |
| ubuntourist | tboimah, when was the domain name set up? | 14:59 |
| tboimah | spencer was the one that give me the domain | 15:00 |
| tboimah | and it was send to him by the client website he is building | 15:00 |
| tboimah | around the 3 of october | 15:01 |
| ubuntourist | OK... So... It should have propagated by now... | 15:01 |
| ubuntourist | I am looking at a "super-verbose" log of an attempt to ssh with the domain name. | 15:03 |
| ubuntourist | adding "-vvv" to the ssh command makes it much more informative for debugging: | 15:03 |
| ubuntourist | ssh -vvv username@host.tld | 15:03 |
| ubuntourist | Also I used the "tee" command to both show the results on the screen | 15:04 |
| ubuntourist | and create a file. | 15:04 |
| ubuntourist | Finally, I told it to send all error messages to the same location as wherever | 15:04 |
| ubuntourist | the standard output was supposed to go, by adding 2>&1 | 15:05 |
| *** tboimah has quit (Remote host closed the connection) | 15:05 | |
| ubuntourist | So the full command is | 15:05 |
| ubuntourist | ssh -vvv username@host.tld 2>&1 | tee ssh.log | 15:05 |
| ubuntourist | that puts all error messages and normal meessages into a file named ssh.log | 15:06 |
| ubuntourist | Give it ONE attempt at the password, then Ctrl-C | 15:08 |
| ubuntourist | Do not try multiple times. | 15:08 |
| ubuntourist | Enter the ip number | 15:14 |
| ubuntourist | And is the passsword typed? | 15:16 |
| ubuntourist | I dont want to hit ENTER if you have not finished typing in the password. | 15:16 |
| ubuntourist | Ignore the debug messages when typing in the password. | 15:17 |
| ubuntourist | Damn. It's freezing on me again. | 15:20 |
| ubuntourist | tboimah, okay... now you should begin to see why that example that we spent sooo much time on | 15:27 |
| ubuntourist | is important. I'm doing the same thing to try to find an error: | 15:27 |
| tboimah | okay | 15:27 |
| ubuntourist | greps, for loops, redirecting the information to a file and the using most on that | 15:27 |
| ubuntourist | file, while searching for specific information. | 15:28 |
| ubuntourist | First I went to the directory with all system logs -- /var/log | 15:28 |
| ubuntourist | Then I looked for any lines that mention "administrator, clean, or cook. | 15:29 |
| ubuntourist | Unfortunately, almost all of the lines contain cleancookingsystem. | 15:29 |
| ubuntourist | But I saved them ot a file named "search-log.txt" anyway. | 15:29 |
| ubuntourist | Inside that file I looked for today's date, so that I would not be getting old | 15:30 |
| ubuntourist | info. | 15:30 |
| ubuntourist | Then I looked for "administrator" happening after that date. | 15:30 |
| ubuntourist | In the file /var/log/auth.log, on October 23 at 02:33:50 there was a pam_unix(sshd:auth) | 15:31 |
| ubuntourist | failure for a user trying to login with the user name "administrator" | 15:31 |
| ubuntourist | I want to see if somehow the user has been permanently locked out for too many | 15:32 |
| ubuntourist | failed attempts. If so, I want to "undo" the permanence. | 15:32 |
| ubuntourist | Gah! This network lag is killing me! | 15:36 |
| *** mulbah has quit (Read error: Connection reset by peer) | 15:40 | |
| ubuntourist | "auth could not identify password for" in the log looks suspicious... | 15:45 |
| ubuntourist | I'm stumped. And late. | 15:47 |
| ubuntourist | Password type in. | 15:49 |
| ubuntourist | Oh MAN is the system slow! | 15:50 |
| ubuntourist | Its saying it will take over 30 minutes to copy that file to newport! | 15:51 |
| tboimah | just leave the instruction since you are getting late i will complete it | 15:51 |
| ubuntourist | OK. | 15:51 |
| ubuntourist | I was trying to get the file to me where I could look at it more and faster. | 15:52 |
| ubuntourist | So when it finishes get the file into e-mail as an attachment. | 15:52 |
| ubuntourist | I THINK the problem is related to something called the PAM system, | 15:52 |
| ubuntourist | but I am not sure. | 15:52 |
| tboimah | okay so we should not contact the web yet right | 15:53 |
| ubuntourist | tboimah, I was trying to search the web for info on what to do about "auth could not identify password for" | 15:54 |
| ubuntourist | which is a phrase I saw in the log. | 15:54 |
| tboimah | because i was about to tell spencer to contact the website he purchase the server from | 15:54 |
| ubuntourist | You may want to research that. | 15:55 |
| tboimah | okay | 15:55 |
| ubuntourist | I think I agree: Don't contact the provider yet. | 15:55 |
| tboimah | Okay | 15:55 |
| ubuntourist | Unless this is a "rush" job and people are complaining a lot. | 15:56 |
| ubuntourist | If people are screaming about not having access, then I guess you can tell Spencer to try anything. | 15:56 |
| ubuntourist | Gotta run! | 15:56 |
| ubuntourist | Bye! | 15:57 |
| tboimah | Okay | 15:57 |
| tboimah | but do you think we can finish the project from now to saturday | 15:57 |
